Please change subscribe by watch and SubscriptionMode by WatchMode bigining with version 1.1.0.

This module help using Apollo queries by binding properties with decorators.

You can query or watch and use an other property for the parameters. Any time a parameter change, a new query is done.

You have to inject an instance of ApolloClient :

import { Container } from 'aurelia-dependency-injection';
import ApolloClient from 'apollo-client';
...
  const apolloClient = new ApolloClient(...);
  Container.instance.registerInstance(ApolloClient, apolloClient);
...

import { ApolloBind } from 'aurelia-apollo-bind';
import gql from 'graphql-tag';

export class ContactList {
  @ApolloBind.query(gql`
query contactList {
  contactList {
    id
    ...
  }
}`)
  contacts;
}

By just changing query by watch, your query will be updated each time an update is done locally or from the server or from an other client.

Each time you change the detailsId property, a new query is done.

import { ApolloBind } from 'aurelia-apollo-bind';
import gql from 'graphql-tag';

export class ContactDetails {
  @ApolloBind.query(gql`
query contactDetails($id: ID) {
  contactDetails(id: $id) {
    id
    ...
  }
}`, 'detailsId')
  details;
  detailsId;
}

import { ApolloBind, WatchMode } from 'aurelia-apollo-bind';
import gql from 'graphql-tag';

export class ContactList {
  @ApolloBind.watch(gql`
query contactList {
  contactList {
    id
    ...
  }
}`, WatchMode.local)
  contacts;
}

If you're pulling the server and don't use ws then the WatchMode can help you to force the sync of your app only locally for this query.

• decorate the class to have general default class inits (pulling time, WatchMode)
• Init the module to force defaults (by default, pulling timing is 500ms and WatchMode is remote)
• Parameter can be an object
• have a decorator like @ApolloBind.local to replace WatchMode.local
• make update similar to the query way with save and revert functionalities.

Any suggestion is welcome !

This is not yet implemented but I need your reactions to make something easy to use and having all the needs.

We can bind functions with the module named contactSave(newData and oldData) and contactRevert(). The save() is called with no-parameter but newData and oldData are transmitted by the module.

export class contactDetails {
  @ApolloBind.query(..., detailsId)
  @ApolloBind.update(gql`
mutation saveContact($id: ID, ...) {
  saveContact(
    id: $id,
    ...
  ) {
    id
    ...
  }
}`)
  details;
  detailsId;

  somewhereElse() {
    if ... detailsSave() ... else ... detailsRevert() ...
  }

  detailsSave(datas?: Promise<{newData, oldData}>) {
    if(datas)
      datas.then((newData, oldData) => console.info('newData, oldData :', newData, oldData));
  }
  detailsRevert() {}
}

contactSave and contactRevert functions don't have to be there in javascript if we don't need the returned promise. In typescript, we need them cause of type cheking.
